To find the equation of the line that passes through the points
and
, we can use the slope-intercept form of a linear equation, which is
, where
is the slope and
is the y-intercept.Step 1: Calculate the slope (
) using the formula:
where
and
are the given points.Substituting the values of the points
and
into the formula, we get:
Step 2: Use the slope-intercept form of a linear equation to find the equation of the line.
Substituting the value of the slope (
) and one of the given points (
) into the equation, we get:
Step 3: Write the equation of the line using the slope-intercept form.
Therefore, the equation of the line that passes through the points
and
is
.
